There will be an increased police presence and likely more bomb-sniffing dogs after the Christmas Day scare on the flight from Amsterdam to Detroit, said Syracuse Aviation Commissioner Tony Mancuso.

The Transportation Security Administration added increased security measures after the incident. A Syracuse TSA official declined to elaborate, saying people should check the TSA Web site for information.

National security officials say a Nigerian national claimed to be acting on al-Qaida's instructions when he attempted to blow up the Airbus plane with 278 passengers aboard. Passengers subdued the man and may have prevented the attack, officials said.
